WBINGER.

Application lletl October 30, 1923. Serial No. 671,731.

`Tl1e invention relates to wringers for expressing water from clothes and other fabrics and relates particularly to a power ,driven wringer although certain features of the wringer may be embodied, with equal success, i'n hand operated wringers.

An object of the invention is to provide a' wringer in which the line of contact between the wringer rolls is clearly and definitely disclosed.'

Another object of the invention is to provide means for immediately relieving the pressure of the rolls upon each other when desired.

Another object of the invention is to provide a wringer in which the pressure on the rolls may be relieved or established with a minimum of effort. Another object of the invention is to provide a wringer in which the upper roll is entirely released from the wrin er when the pressure of the rolls is release The invention possesses other advantageous features, some of which, with #the foregoing, will be set forth at length in the following description, where We shall outline in full, the form of the invention which we have selected for illustration in the drawings accompanying and formin part` ofthe present specification. In sai drawings we have shown one form of wring\ er embodying our invention, but it is to be understood that we do not limit ourselves to such form, since the invention, as set forth in the claims, may be embodied in a plurali ity of forms.

Referring to said drawin s:-

Figure 1 is a front elevation of a wringer embodying our invention.

Figure 2 is a side elevation of the wringer with the parts in position to place the rolls under pressure. v

Figure 3 is a side elevation of the wringer with"the parts in position to release 'the upper roll.

Figure 4 is a perspective view of one of the mountings of the upper wringer roll.

The wringer of our invention comprises a stationary support consisting of the end plates 3 in which the lower roll 4 is Journalled.I The roll-4 is provided with a driving shaft 5 which may be operated by hand or power. Each side plate 3 is provided on its outer surface with an ear 6fto which a curved flat spring 7 is secured. The upper roll 8 is journalled in the free end of the spring 7 and the spring is so constructed that'it exerts a downward pressure on the upper roll 8, pressing it against the lower roll 4, so that water is expressed from fabric passing between the rolls. The spring 7 1s resilient and permits the upper roll 8 to move upward when material is disposed between the rolls.

The rolls 4 and 8 are made of contrasting appearance, preferably by making the two rolls of different color, so that the line of contact of the rolls is always definitely disclosed, thus obviating the necessity of the housewife feeling for the line of contact and sometimes having her fingers caught, due to the obscurity of the line of contact. A We prefer to make the rolls of different colors,

for instance the lower roll white and .the

upper roll blue, but the same desirable effect v may be `obtained by forming designs of different configuration on the surfaces of the rollers, so that the interruption of the designs on the two rollers will clearly indicate the line of contact.

Means are provided for releasing the pressure of the rolls and for releasing the upper roll from its bearing. Each spring 7 is providedl on its end wlth a cylindrical bearing member 12 which is preferably integral with the sprin The bearing member 12 .is preferably ndisposed vertically above the axis of the roll 4 and is pressed downward towards the roll 4 by the spring 7. Journalled in the bearings 12 are the t-runnfions 13 of the release member 14 which normally overlies the upper roll 8. The trunnions 13 of the release member 14 are provided with eccentrically-disposed bearings 15 which open laterally onto theB faces of the trunnions. Disposed in the bearings 15 are the trunnions or shaft ends 16 of the upper roller 8. By virtue of the fact that the bearings 15 open laterally onto the surface of the trunnions 13, the shaft ends 16 of the roller may be readily dropped into these bearings.v To permit the removal of the roller 8 from the bearings 15 the cylindrical bearing members 12 are each provided with an a erture or notch 17 ios when the aperture in the bearing is alined with the aperture 17. The trunnions 13 are rotatable in the bearings 12 to expose the bearing 15in the aperture 17 so that the roll 8 may be readily removed and replaced. ,g

The trunnions 13 are rotated by movmg the release member 14 and the movement of this member is limited by the pin 18 which extends into the aperture 17. When the member 14 is in its backward position the pin 18 lies in the notch 19 so that it will not interfere with the outward movement of the shaft rnd 16, from the bearing.

Normally the parts are in the position shown in Figure 2, the spring serving to press the rolls together. 1n this position, the axis of the trunnion 13 is slightly displaced from the line of dead center of the axes of the two rolls 1 and 8 so that the pressure of the rolls does not tend to rotate the release member 14 and thus relieve the pressure on the roll. The axis of the trunnion 13 is slightly in front of the line through the axis ofthe rolls so that the parts are securelyV held in operative position. When it becomes necessary or desirable to relieve the pressure of the rolls, the release member is moved backward b a slight pressure of the hand and when t e center of the trunnion passes dead center, the .release member springs into the position shown in Figure 3. With the release member in this position, the trunnion 13 has rotated suiiciently to bring the opening of the bearing 15 into registry with the aperture 17 so that the roll 8 is freed and may be lifted from the wrmger.

Means are provided for receiving the pressure of the springs 7 when the release member is operated so that the pressure ma be transferred from the wringer rolls. is-

posed on`the plate 3 below the bearin mem-V ber 12 is a stop 21 with which the caring member contacts as thetrunnion 13 is rotated. The pressure of the spring is thus transferred from the roller 8 to the stop 21 so that the roller 8 is entirely free and may be removed from the wringer. With the f shaft ends 16 of the roller 8 in position in the bearings 15, and with any obstruction removed from between the rolls, the release member may be easily moved forward to the position shown in Figure 2, such movement serving to lock the shaft ends 16 in their bearings and to transfer the pressure of the springs from the stop 21 to the roller 8. We claim: .e

1. In a wringer, a pair of movable bearings each having a lateral aperture therein, a release member, trunnions on said release release member, trunnions on said release member journalled in said bearings, each of said trunnions having an eccentric bearing therein opening laterally on the face of the trunnion and adapted in one position to reg-- ister with said aperture, a roll, and trunnions on said roll adapted to be moved through said apertures into and out of said 4 eccentric bearings.

3. In a wringer, a stationary frame, a movable normally upright release member having bearings, an upper wringer roll'journa-led in said bearings, means for operatively connecting said release member to said stationary frame, means for freeing the upper roll from said release member upon movement of said member to an inclined position, and means for causing said roll to be retained in opera-tive posltion upon movement of said member to its upright position.

4. In a wringer, a pair of rolls normally mounted 1in superposed relation, spring means for resiliently pressing said rolls together, means for varying the pressure between said rolls including a manually convtrolled lever having limlte'd movement to from its mounting when said lever is in said secondposition only.

5. A wringer comprising a stationary support in which is journalled a lower wringer roll, spring arms provided with apertured bearings carried by said stationary support,

a rotatable release-f member journalled in said 4 bearings and normally closing said apertures, and an' upper wrlnger roll eccentrically supported within said bearings and rev leasably secured therein by said release member when said apertures are closed.

In testimony whereof, we have hereunto set our hands.
